Quick Start


Changes for Version 5 Release 1--March 2002

The following changes have been made to the product for this edition:

Tivoli Storage Manager Device Driver
The Tivoli Storage Manager Server device driver is now available on HP-UX. It replaces the use of the SCSI Pass-through driver for autochangers, and can be used to optimally support SCSI tape and optical drives.

See Tivoli(R) Storage Manager Administrator's Reference.

LAN-Free Data Movement
Tivoli Storage Manager supports LAN-free data movement in storage area network (SAN) environments. The support allows client data to move directly from the client system to a server-managed storage device on the SAN. This enhancement reduces data movement on the LAN so that more bandwidth is available to other applications.

See Tivoli Storage Manager Administrator's Reference and Tivoli Storage Manager Managed System for SAN Storage Agent User's Guide for more information.

Devices Attached to HP Systems that Use Precision Bus SCSI Adapters
Devices attached to HP systems that use Precision Bus SCSI adapters are no longer supported. This is because the architecture is no longer current. If you are using such a system, do not migrate to Version 5.1.

Changes in Defining Drives and Libraries

Device special file names and External Library managers are now specified in the DEFINE PATH and UPDATE PATH commands, rather than in the DEFINE DRIVE, UPDATE DRIVE, DEFINE LIBRARY, and UPDATE LIBRARY commands.

See Adding a Manual Library, Adding an Automated Tape Library and Tivoli Storage Manager Administrator's Reference.

Moving Data by Node
You can use the MOVE NODEDATA command to move data in a sequential-access storage pool for one or more nodes, or move selected file spaces for a single node. You can also use MOVE NODEDATA to move data to another storage pool.

See Tivoli Storage Manager Administrator's Reference.

Support for Simultaneous Writes to Primary and Copy Storage Pools
You can specify copy storage pools in a primary storage pool definition. When a client backs up, archives, or migrates a file, the file is written to the primary storage pool and is simultaneously stored into each copy storage pool.

See Tivoli Storage Manager Administrator's Reference.

Tivoli Data Protection for New Network Data Management Protocol Support

New Network Data Management Protocol (NDMP) support now extends to the HP-UX (32-bit and 64-bit) Tivoli Storage Manager server platform. The new Tivoli Data Protection for NDMP product supports NDMP backup and restore for network-attached storage (NAS) file servers and Network Appliance. NDMP allows a network storage-management application to control the backup and restore of an NDMP-compliant file server without installing third-party software on that server. The NAS file server does not require installation of TSM software. The TSM server uses NDMP to connect to the NAS file server to initiate, control, and monitor a file system backup or restore operation. The NDMP support for NAS file servers enables higher performance backup to tape devices without moving the data over the LAN. TDP for NDMP is a separately priced and licensed product.

See Tivoli Storage Manager Administrator's Reference.

Data Validation with Cyclic Redundancy Checking
Tivoli Storage Manager provides the option of specifying whether a cyclic redundancy check (CRC) is performed during a client session with the server, or for storage pools. The server validates the data by using a cyclic redundancy check which can help identify data corruption. Data validation can be enabled for one or all of the following:

See Tivoli Storage Manager Managed System for SAN Storage Agent User's Guide and Tivoli Storage Manager Administrator's Guidefor more information.

New Licensing Method
The new licensing method enables you to register the exact number of licenses that are required, rather than in increments of 1, 5, 10, and 50.

See Licensing Wizard and Tivoli Storage Manager Administrator's Reference.
